The Valentines all measure 640x875, making them the perfect size for printing out for whatever Valentine you choo-choo-choose. Or go ahead and save them to your desktop (right click, save as). Post them on your Tumblr, Tweet them at your friends, paste one on that special someone's Facebook wall, or pin them all on your Pinterest board. Attach one in an email and send it off to your book loving friends. Whatever you need to do to let that special someone know you care.
